METHOD OF MAKING FILLING OR TRAM FOR SILK FABRICS.

SPECIFICATION forming part of Letters Patent No. 358,489, dated March 1, 1887.

Application filed March 21, 1885.

. which Figure 1 is a plan view of myimproved silk fabric. Fig. 2 is an enlarged-cross-section of a raw-silk thread as used therein. Fig. 3 is an enlarged side View of the tram used in the fabric.

This invention relates to a new method of making a filling or tram forsilk fabric,in which the shuttle threads are each composed of a series of tram threads that lie substantially parallel to one another in the weft.

I proceed in the following manner to make a shuttle thread or filling for my fabric: First, a series of cocoon-threads,a a, Fig.2, are united by their natural gum and formed into a rawsilk thread, '1). Of such raw-silk threads two Serial No.1i39,627. (No model.)

or more are then doubled and twisted together, thus forming a traurthread, d, and a series of these tram-threads d (7, thus produced, are doubled again and twisted but,after dyeing, the second twist is taken out of them, leaving the whole filling A composed of a series of tram-threads, cl, that lie substantially parallel to one another, as in Fig. 3.

In producing asilk fabric with my improved tram A therein, I interlock the warp threads ewith the compound tram-threads A by means of the ordinary mechanism.

What I claim is- The method herein described of preparing filling for silk fabrics, consisting in doubling and twisting a number of raw-silk threads to form tram-threads, doubling and twisting a number of these tram threads, dyeing the suliist-antially as described.
